#3072 Rb and p53 Status Determination by Immunochemistry Is Complementary in Routine Practice to Genetic Testing of Neuroendocrine Neoplasms

Introduction: Rb and p53 status may help distinguishing well from poorly differentiated neuroendocrine neoplasms (NEN) and may predict response to chemotherapy. Studies correlating Rb/p53 genetic and immunohistochemistry were performed on high-quality frozen samples with high throughput techniques efficient for copy number determination. This situation differs from routine practice in which small deletions may be hard to detect on formalin-fixed paraffin-embedded (FFPE) samples with a gene panel approach.

#3013 Structurally-Optimized Peptide VMT-Alpha-NET Enhances the Efficacy of SSTR2-Targeted Alpha-Particle Therapy for Neuroendocrine Tumors

Introduction: 203Pb/212Pb is a promising theranostics pair for SSTR2-targeted alpha-particle therapy for neuroendocrine tumors (NETs). The development of SSTR2-targeted peptides that are optimized for the Pb isotopes has the potential to improve performance.

#2998 Inter- and Intrapatient Mean Absorbed Dose Variation and Simplification of Dosimetric Workflow after PRRT

Introduction: Post-PRRT dosimetry is not routinely performed, partly due to required multiple imaging time points. One time point imaging would reduce patient burden, and make dosimetry more applicable in the clinical settings.

#2991 Gastroenteropancreatic (GEP) Neuroendocrine Neoplasia G3 (NEN G3) According to 2019 WHO Classification: A Comprehensive Clinicopathological Characterization Including Mismatch Repair (MMR) Proteins, PDL1 Expression and KRAS/BRAF Status

Introduction: In the 2019 WHO FOR NEN’S classification NETG3 have been distinguished from poorly differentiated neuroendocrine carcinoma (NEC). They are heterogeneous group concerning prognosis and treatment benefit.

#2982 Comprehensive Molecular Analysis Identifies Driver Mutations in Metastases of Sporadic Well-Differentiated Neuroendocrine Tumours of the Small Intestine

Introduction: Small intestinal neuroendocrine tumours (SI-NETs) represent a heterogenous group of tumours. The molecular mechanisms which contribute to progression of SI-NETs are poorly elucidated. They are considered to be molecularly distinct from neuroendocrine carcinomas (NECs), which share oncogenic pathways with adenocarcinomas.
